aftermarket brake master cylinder

Has anyone tried an r6 or similar master cylinder on the Bandit. 

I know Dekenai us running a Brembo RCS 19, but I was thinking bang for buck. Might just bite the bullet and get a brand new Brembo at least then I don't have to stuff about rebuilding a used mc

I`ve been running an 07-08 gixx 1000 master since 2007, and to be honest, along with braided lines at the same time, I noticed little difference.

I will go down the Brembo path when I get around to it, along with callipers.

I reckon Suzuki brakes are soft even gsxrs. If you try Yamaha or Kawasaki brakes they are super sensitive

I recon save and go Brembo.

I`ve been watching them on ebay for the last two years, and sometimes there`s some pretty good deals.

I found this on the Internet.
I would be cautious about using GSXR master cylinders.

according to the National Highway Traffic Safety Administration (NHTSA). The bikes are being recalled because of corrosion of the brake piston (in combination with older brake fluid) inside the front brake master cylinder that generates gas that may result in reduction of fluid pressure transmission to the front brake. As a result, front braking power may be reduced and increase the risk of a crash.
The bikes being recalled include certain model year 2004-2013 GSX-R600s and GSX-R750s and 2005-2013 GSX-R1000s.
Suzuki will be contacting owners of the affected units, who in turn can take their GSX-Rs to Suzuki dealers for a free replacement of the front master cylinder. The recall will begin on November 4.
In a letter dated October 18, 2013 Suzuki Motor of America said: “After a long-term service life of the motorcycle without changing the brake fluid, the brake fluid can deteriorate and absorb moisture. The brake piston inside the front brake master cylinder may not have uniform surface treatment. This combination of conditions can lead to corrosion of the brake piston.” This corrosion contributes to the generation of gas and due to the side position of the reservoir, may not be “adequately purged from the master cylinder.”
As the gas accumulates the front brake lever “may develop a ‘spongy’ feel and stopping distances may be extended, increasing the risk of a crash.”

This post is probably a good reminder that we should fully bleed the brake systems at some point, completely replacing the old fluid with new stuff (another item not included in the servicing schedule if I remember right).  Might do that tomorrow.

When the K7/8 gixxer front-end was installed, was expecting a major improvement in the brakes and was pretty disappointed.  Had previously tried (standard front-end), Ferodo HH pads, (little but not a lot better), galfer stainless lines, (again a little better; and what a pain in the arse bleeding the ABS was!), and gsxr radial m/cylinder.  The sum of all this was; better but still lacking in the power and feel to give you real confidence.
Next came the full gixxer transplant with Braking SK1 wave discs, which was still lacking…so enter the RCS19 m/cylinder which transformed the system into something very confidence inspiring.


 
My guess is that you could achieve the same result using the m/cylinder from a CBR or ZX, which both use the same or very similar calipers to the pre-Brembo  gixxers and have very good brakes.
Incidentally, my gut feel is that there is little gain in the OEM Suzuki/Brembos.  They look like OEM cheapies and I doubt are significantly better than the monbloc Tokico’s they replaced.
The setup on the K9 trackie uses the Monobloc Tokico’s, Braking ‘Batfly’ discs, Braking P1 pads, Brembo RCS19, Galfer superbike lines…this combination provides huge power and feel, even better than the Brembo goldline setup on the Bimota YB11.


 
Incidentally, here is a shot of the current project…a bit of a ‘track’ dash (mocked up in cardboard) to mount the lap timer and gear indicator…gixxer already has one standaxd, (gear indicator) but is hard find in a quick scan.


 

If you do decide to go RCS19 then I can recommend Omnia Racing or Carpi Moto.  Both do GST (VAT) exempt for non-EU residents and that makes them about 200 Euro.
